CONTAINER ron 'raANsronrINe AND MIXING CONCRETE l Application 'med December 15, 1928. serial No. 326,303.

My invention relates to containers or drums such as are used on vehicles for transporting mixedconcrete, and particularly to the type of vehicle shown in my co-pending applica- .5 tion Ser. No. 319,630, filed November 15, 1928. It relates specifically to an improved drum structure which facilitates the rapid filling and emptying of a non-tilting drum.

In the type of containers now in u se, considerable equipment is required to insure proper deliveryof the material inside of the containerthrpugh the opening thereof. The most common type of drum is one mounted with tilting equipment for end delivery. It

is not alwayseasy to insure complete iow of the concrete therefrom; but in any event the tilting equipment is costly and cumbersome. In my co-pending application above referred to, I have described and claimed a type of transporting equipment, in which the drum does notltilt, butis held horizontally, and lled and emptied through a closable port. In this type also it is sometimes difficult to insure complete emptying; and frequently the material has had to be assisted through the l ort. Any mixing baffles inside the container liave always hindered rather than facilitatedl the'emptying of it.

It is an object of my invention to provide a horizontal and non-tilting drum which may be completely emptied very quickly and easily. f

It is another object of my invention to provide means within the drum for guiding the material to the port, which means will also facilitate the mixing" of the .concrete during transportation. y

Another object is to provide a drum with an improved outlet or port, which is easily operable, and is not resisted in opening by the material within the-drum. v

These and other objects of my invention which will be more specically pointed out in the ensuing disclosure, or will be obvious therefrom to one skilled in the art, I accomplish by that certain construction and arv ing had to the drawings which accompany these specifications.

I have shown a cylindrical drum l with tapered ends 2 terminating in a flat surface 3 upon which is fastened a ianged bearing 4 for mounting the container on a shaft 5. This shaft is mounted and free to rotate in bearf ings provided on vehicles such as shown in my copending application above referred to. It will be understood that mixed concrete isv transported upon such vehicles in the drum, and that thevdrum is kept revolving during such transportation.v

Within the drum I locate plates 6 fastened to the drum as bywelding, and slanting from the tapered ends of the drum toward av port, presently to be described, located in the side of the drum between the ends. 7 is also disposed at an angle within the drum, and slants from the port toward a position on the side of the drum, and between the first plates. Tight joints are made at all meeting lines between the plates, and the plates and nthe drum. When the drum is disposed as shown in Figure 3, these plates form a hopper to conduct material toward the port. All three plates terminate on another plate 8 which forms the bottom of a built-in chute, and the side plates 9 and plate 8 form the rectangular discharge opening for my container. This opening is on a line tangent with the outside of the cylinder formingmy drum.

On the outside of my discharge opening I Another plate have xedly mounted valve gate guides 10 with grooves 11 in which tongues 12 on the valve-gate 12a are free to slide. On each side of the valve-gate I have fixedly mounted a rack 13a for sliding the valve-gate in its retaining grooves. Meshing with the racks are two spur gears 13 xedly mounted on a shaft 14 which is rotatively mounted in bearings 15. These bearings are fixed to the valvegate guides which are alsorigidly mounted on the container. The ends of the shaft 14 have been squared so as to receive a socket wrench 16 which is the means provided for turning the shaft and gears thereon and thereby opening or closing the valve.

At the top of my drum I have provided an opening 17 with a closing cap 18 to permit of cleaning or loading my? drum, or flushing it with water.

When my drum is mounted on a vehicle it can be rotated or held stationary as desired. It is my intention to rotate the drum especially while transporting the material, thereby keeping it properly mixed and soft. It will be seen that the guide plates within my container will also act as batlies and agitate the material so that there will be constant intermixing of the ingredients. When I Wish to unload my drum, I turn it into the position shown in Figure 3, and open the valve gate the desired amount. The material readily flows from within the drum because it is iowing over sloping guides forming a hopper and. directing it to the port.. Y

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In combination with a vehicle for transporting mixed materials, a rotatable non-tilting drum with an outlet port, said port having a bottom wall extending tangentially to the walls of said drum, and bailiing meansI within said drum disposed to direct the flow of material toward said port.

2. A device for handling mixed materials, a rotatable drum having/an outlet port with a removable closure, said port having a hottom wall extending tangentially to the walls of said drum, said drum constructed and arranged to form a hopper to direct material toward said port.

3. A device for handling mixed materials, a rotatable drum having an outlet port with a removable closure, and members Within said drum forming a hopper to direct material toward said port, said closure located approximately tangentially to said drum, and said hopper terminating in a chute, the sides of which form said port.

4. A. device for handling mixed materials,

'a rotatable drum having an outlet port with a removable closure, and members within said drum forming a hopper to direct material toward said port, said closure located approximately tangentially to said drum, and said hopper 'terminating in a chute, the sides of whichA form said port, said chute and said closure forming part of the wall of said drum.

5. In a device for handling mixed concrete,

.able closure for said port.

a horizontally pivoted, non-tilting drum, plates disposed within said drum to form a hopper, members defining an outlet port disposed substantially tangentially to said drum, a plate disposed substantially tangentially to said drum and substantially at right angles to said port forming a chute, the portion of said drum between said port and said plate cut away, said hopper disposed to conduct material through said opening, suitable plates closing the sides of said chute, and a remov- ARTHUR o.
